Title: Improvements in combined forging and trimming method and apparatus
IPC: B23D27/00
Filed: 1955-06-24
Abstract: 771,639. Forging; trimming. NATIONAL LEAD CO. June 24, 1955 [July 8, 1954], No. 18307/55. Class 83 (4). A method of forging metal articles and trimming the flash therefrom, comprises forging a heated metal slug into a shaped article in a forging die A, B, and then trimming in a trim die having upper and lower parts 19, 17 respectively, the flash from the forging, the upper part 19 of the trim die being evacuated during the trimming operation so as to retain the trimmed forging therein during its upstroke, the trimmed forging being subsequently ejected from the upper part by an ejector 22. The stationary lower part B of the forging die receives a heated slug whereupon the upper die A is closed thereon and a forging ram 13 actuated by a pneumatic plunger 14 is moved upwardly to upset the slug into the closed die cavity, flash being produced at the joint between the die halves. On the upstroke of the upper die, the forging is retained therein and is subsequently ejected therefrom by an ejector 11 actuated through rack-and-pinion mechanism, Fig. 3 (not shown), by an hydraulic motor. The ejected forging drops into the lower trim die 17 which is mounted on a slide 15 movable by a motor 16. The slide 15 is then withdrawn to position the lower trim die 17 into alignment with the upper trim die 19 which is subsequently lowered whereby its shearing edge 20 severs the flash whilst the forging is still hot, simultaneously depressing a spring-loaded stripper ring 25. During the trimming the upper die 19 is evacuated through a port 21 so as to retain the forging therein during the upstroke. The flash is removed from the lower die 17 by the stripper ring 25 and is blown clear by an air blast. The trimmed forging may be cooled by a stream of air, or may be permitted to cool naturally, whilst in the upper trim die and is then removed therefrom by the ejector 22 actuated by an hydraulic motor. Meanwhile the slide 15 has moved inwardly so that the ejected forging drops into a shoot 18 carried by the slide. Alignment means 23, 24 are provided for the trim die. The various movements of the apparatus are performed automatically in the correct sequence including the retraction of the forging ram 13.

Title: A reciprocating electric motor
IPC: H02K7/065
Filed: 1952-07-23
Abstract: 715,429. Reciprocating motors. TESLA, NARODNI PODNIK. July 23, 1952 [July 24, 1951], No. 18626/52. Class 35 An electromagnetic device for producing continuous movement along a straight or curved rod 1 comprises a heavy electromagnet core 2, 3 sliding on the rod with little friction, and a comparatively light armature 5 sliding with considerable friction, the armature and electromagnet being resiliently connected together. In the form shown in Fig. 1, energization of the coil 16 or 17 of either electromagnet core through contact 13 or 14 with current impulses, half-wave rectified A.C. (as shown), or with alternating current, causes the armature to be jerked towards the core 2 or 3. When the current impulse is over, the springs 18-21 readjust the relative positions by drawing the electromagnet member into the same position relative to the armature which is secured in position by its comparatively great friction, so that the unit progresses step-by-step along the rod. The armature friction is adjustable by a spring-loaded pad 8 bearirig on the rod 1. In the modification shown in Fig. 2; the armature is secured to the rod 1 by means of a guide 22 which normally allows free movement on the rod but when force is applied at 30 or 31 by either electromagnet the tilting force causes the sleeve to bind on the rod and prevent motion of the armature. As a result, the electromagnet body moves along the rod and when the current impulse is passed, springs 28, 29 draw the armature along the rod to a new equilibrium position so that continuous motion along the rod is produced in a direction depending on which coil is energized. If desired, the device may have only one electromagnet core and so produce motion in one direction only.

Title: Improvements in or relating to electric gaseous discharge tubes
Inventor: KLEPP GEORGE FRANCIS
IPC: H01J17/48
Filed: 1952-07-23
Abstract: 730,033. Cold-cathode tubes. STANDARD TELEPHONES & CABLES, Ltd. July 23, 1952, No. 18630/52. Class 39(1). A method of manufacture of a cold cathode gas-filled electric glow discharge tube suitable for providing a reference voltage comprises the step of adjusting the pressure of the gas filling, prior to sealing off the envelope of the tube, so that under given operating conditions of normal glow discharge in the sealed-off tube, the temperature coefficient of anode-cathode maintaining voltage is substantially zero. It is stated that rather than to take measurements of the actual temperature coefficient involved, it has been found that the difference, for various gas pressures, between the anode-cathode maintaining voltage for a given cathode current immediately after switching on and after thermal equilibrium has been attained provides a sufficient measure of the relationship between the gas pressure and the temperature coefficient. The curve shown relates to a voltage reference tube having a cylindrical nickel cathode activated by cerium-mischmetal and surrounding a rod anode, the gas filling being 97 per cent neon and 3 per cent argon at an ambient temperature of 20 C. The curve shows that the filling pressure could be adjusted to provide any given positive or negative temperature coefficient within the limits of variation of this quantity. Similar results may be obtained when the gas mixture varies between 94 and 99 per cent neon, the remainder being argon, and also for a neon, helium, argon mixture in the ratio of 80: 20: 1.

Title: Improvements in or relating to process for pulverizing solid materials
IPC: B01J8/18
Filed: 1953-07-07
Abstract: 746,056. Disintegrating-apparatus; granulating metal. TEXACO DEVELOPMENT CORPORATION. July 7, 1953 [July 10, 1952], No. 18790/53. Classes 59 and 82(2). A process for pulverizing a solid material comprises mixing the solid material in particle form with a liquefied normally gaseous refrigerant, forming the mixture into a confined stream, heating the mixture whereby the refrigerant is vapourized to form a dispersion of solid particles in a stream of the resulting vapour, and subjecting the dispersion to highly turbulent flow, the velocity and turbulence of the dispersion being at least sufficient to shatter and largely reduce the particles to powdered form. In the apparatus shown, solid material is introduced through line 5 to a mixer 6 to which liquefied refrigerant is supplied through line 7 in an amount sufficient to form a slurry of the solid in the refrigerant. The slurry is passed by a pump 8 through a vapourizer coil 9 which is heated by means of a water jacket 10. From the coil 9, the refrigerant and entrained solid is passed to a further coil 11 which may be provided with a water jacket 12. Water for heating the jackets 10, 12 is circulated through a heater 14 by means of a pump 13. The gasiform dispersion of particles in vapour is discharged from the coil 11 into a cyclone separator 16 from which the pulverized solid is discharged through line 17 while the separated vapours are compressed by a compressor 18 and passed to a condenser 19, the condensate being returned to the mixer 6. The solid material may be charged into the mixer under pressure. The solid materials to be pulverized include resins, waxes, metals and metal alloys, oil-bearing seeds and nuts, cellulosic materials, chemicals, and starchy materials. Refrigerants quoted are ammonia, carbon dioxide, liquefied petroleum gases, and halogen derivatives of low boiling hydrocarbons. The solid particles supplied to the mixer preferably have a size within the range # inch to 325 mesh. The velocity of the slurry in the confined stream is preferably within the range ¢ to about 10 feet per second while the velocity of the gaseous dispersion should be greater than about 100 feet per second. The path of the gaseous dispersion preferably has a length greater than 100 times its diameter. Specification 683,318 is referred to.
